Supplier Agreement: H100

Contract Change Order: 123

We have a customer who has licenses for Contract Change Management but not for Sub Contract. 

The customer needs to have track of the supplier agreements changes. We are thinking about how we can fulfill the customer requirement using Supplier agreement and Contract Change Management.

I know that is possible to use Object connections and attach the Contract change order to the Supplier agreement: 

however, it is not possible to progress the Contract change order with a change type  ‘Supplier’, because the sub contract number is required, and as I mentioned before, the customer does not have sub contract license.

On the other hand, it is not possible to progress the Contract change order without change type: 

It is possible to link the supplier agreement with a contract change order without using Sub contract and progress with the Contract change order flow? if so, how can I proceed?

Thanks in advance.
